QUESTION 225
You have a private distribution group that contains provisioned and unprovisioned devices.
You need to distribute a new iOS application to the distribution group by using Microsoft Visual Studio App Center.
What should you do?
A. Generate a new .p12 file for each device.
B. Create an unsigned build.
C. Register the devices on the Apple Developer portal.
D. Create an active subscription in App Center Test.
Answer: C
Explanation:
When releasing an iOS app signed with an ad-hoc or development provisioning profile, you must obtain tester’s device IDs (UDIDs), and add them to the provisioning profile before compiling a release. When you enable the distribution group’s Automatically manage devices setting, App Center automates the before mentioned operations and removes the constraint for you to perform any manual tasks. As part of automating the workflow, you must provide the user name and password for your Apple ID and your production certificate in a .p12 format.
App Center starts the automated tasks when you distribute a new release or one of your testers registers a new device. First, all devices from the target distribution group will be registered, using your Apple ID, in your developer portal and all provisioning profiles used in the app will be generated with both new and existing device ID. Afterward, the newly generated provisioning profiles are downloaded to App Center servers.

You need to run a URL ping test once every five minutes and create an alert when the web app is unavailable from specific Azure regions. The solution must minimize development time.
What should you do?
A. Create an Azure Monitor Availability metric and alert.
B. Create an Azure Application Insights availability test and alert.
C. Write an Azure function and deploy the function to the specific regions.
D. Create an Azure Service Health alert for the specific regions.
Answer: B
Explanation:
There are three types of Application Insights availability tests:
URL ping test: a simple test that you can create in the Azure portal.
Multi-step web test
Custom Track Availability Tests
Note: After you’ve deployed your web app/website, you can set up recurring tests to monitor availability and responsiveness. Azure Application Insights sends web requests to your application at regular intervals from points around the world. It can alert you if your application isn’t responding, or if it responds too slowly.
You can set up availability tests for any HTTP or HTTPS endpoint that is accessible from the public internet. You don’t have to make any changes to the website you’re testing. In fact, it doesn’t even have to be a site you own. You can test the availability of a REST API that your service depends on.

QUESTION 242
You plan to provision a self-hosted Linux agent.
Which authentication mechanism should you use to register the self-hosted agent?
A. personal access token (PAT)
B. SSH key
C. Alternate credentials
D. certificate
Answer: A
Explanation:
Note: PAT Supported only on Azure Pipelines and TFS 2017 and newer. After you choose PAT, paste the PAT token you created into the command prompt window.

QUESTION 246
You have a build pipeline in Azure Pipelines that uses different jobs to compile an application for 10 different architectures.
The build pipeline takes approximately one day to complete.
You need to reduce the time it takes to execute the build pipeline.
Which two actions should you perform? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
A. Move to a blue/green deployment pattern
B. Create a deployment group
C. Increase the number of parallel jobs
D. Reduce the size of the repository
E. Create an agent pool
Answer: CE
Explanation:
Question: I need more hosted build resources. What can I do?
Answer: The Azure Pipelines pool provides all Azure DevOps organizations with cloud-hosted build agents and free build minutes each month. If you need more Microsoft-hosted build resources, or need to run more jobs in parallel, then you can either:
– Host your own agents on infrastructure that you manage.
– Buy additional parallel jobs.
Reference:
https://docs.microsoft.com/en-us/azure/devops/pipelines/agents/pools-queues
QUESTION 247
You are creating a build pipeline in Azure Pipelines.
You define several tests that might fail due to third-party applications.
You need to ensure that the build pipeline completes successfully if the third-party applications are unavailable.
What should you do?
A. Configure the build pipeline to use parallel jobs
B. Configure flaky tests
C. Increase the test pass percentage
D. Add the Requirements quality widget to your dashboard
Answer: B
Explanation:
Flaky tests present a barrier to finding real problems, since the failures often don’t relate to the changes being tested. A flaky test is a test that provides different outcomes, such as pass or fail, even when there are no changes in the source code or execution environment.
Reference:
https://docs.microsoft.com/en-us/azure/devops/pipelines/test/flaky-test-management?view=azure-devops
QUESTION 248
Your company is building a new solution in Java.

You need to analyze and monitor the code quality of the Java solution.
Which task types should you add to the build pipeline?
A. Gradle
B. Chef
C. Grunt
D. Gulp
Answer: A
Explanation:
SonarQube is a set of static analyzers that can be used to identify areas of improvement in your code. It allows you to analyze the technical debt in your project and keep track of it in the future. With Maven and Gradle build tasks, you can run SonarQube analysis with minimal setup in a new or existing Azure DevOps Services build task.
Prepare Analysis Configuration task, to configure all the required settings before executing the build.
– This task is mandatory.
– In case of .NET solutions or Java projects, it helps to integrate seamlessly with MSBuild, Maven and Gradle tasks.
Note: There are several versions of this question in the exam. The question can have three correct answers:
– MSBuild
– Maven
– Gradle
The question can also have different incorrect options, including:
– Chef
– Octopus
– xCODE

– Stores shared values as key/value pairs that can be used by all the apps
Which Azure service should you recommend as the configuration management solution?
A. Azure Cosmos DB
B. Azure App Service
C. Azure App Configuration
D. Azure Key Vault
Answer: C
Explanation:
The Feature Manager in the Azure portal for App Configuration provides a UI for creating and managing the feature flags that you use in your applications.
App Configuration offers the following benefits:
A fully managed service that can be set up in minutes
Flexible key representations and mappings
Tagging with labels
Point-in-time replay of settings
Dedicated UI for feature flag management
Comparison of two sets of configurations on custom-defined dimensions
Enhanced security through Azure-managed identities
Encryption of sensitive information at rest and in transit
Native integration with popular frameworks
App Configuration complements Azure Key Vault, which is used to store application secrets.

QUESTION 250
You have a containerized solution that runs in Azure Container Instances. The solution contains a frontend container named App1 and a backend container named DB1. DB1 loads a large amount of data during startup.
You need to verify that DB1 can handle incoming requests before users can submit requests to App1.
What should you configure?
A. a liveness probe
B. a performance log
C. a readiness probe
D. an Azure Load Balancer health probe
Answer: C
Explanation:
For containerized applications that serve traffic, you might want to verify that your container is ready to handle incoming requests. Azure Container Instances supports readiness probes to include configurations so that your container can’t be accessed under certain conditions.
Incorrect Answers:
A: Containerized applications may run for extended periods of time, resulting in broken states that may need to be repaired by restarting the container. Azure Container Instances supports liveness probes so that you can configure your containers within your container group to restart if critical functionality is not working.
